58 through 71 are lanthanides, 90 through 103 are actinides.
Lanthanoids (formerly called Lantanides).
Ray
Elements 90-103 are the actinide series, the actinides, or actinoids. Many periodic tables identify these elements as elements 89-103, which include the element actinium.
the lanthanide series
Actinoids.
Actinides
Lantanyde and actinyde
The elements are called Actinides. They are placed at the bottom of periodic table. These elements have different properties.These elements are in the f group of the periodic table. Elements from Ac-Lr belong to this group. These are called Actinides.
The elements with atomic numbers 58 to 71 are called Lanthanides or Lanthanoids. This literally means "Like Lanthanum". They are called this because they have similar characteristics to Lanthanum.
Actidines.
Sucrose is comprised of 3 elements (Carbon, Hydrogen and Oxygen), and since there are 103 known elements, the remaining 100 elements are not found in sugar.-S.M.
Elements 89 (Actinium) through 103 (Lawrencium) on the periodic table of elements.
The Actinides.
Lantanyde and actinyde
103
Actinide Series.
Any of a series of chemically similar, radioactive elements with atomic numbers ranging from 89 (actinium) through 103 (lawrencium). they are outer transition elements All of these elements are radioactive, and two of the elements, uranium and plutonium, are used to generate nuclear energy
